Group switch Clock Alarm

[himate]

Hi all


I have a problem with the clocking on a remote site's group switch. The following errors show;

<ALLOP;

As can be seen, the MCCL is not signalling and I assume is the cause of the problem. I also see that no RCCL has been setup.

Do I change the MCCL link to GSMULT 0-1 and also set the RCCL on 2-2-00-0?
Also is the INTERNAL SYNC ERROR from the SCEXP print another problem or part of the same?

thanks...

Initiate RCCL in LIM2. Don't touch MCCL, it doesn't matter if it is signalling or not. After initiating RCCL, ALREI and SCEXP the system again. It take several seconds to establish the sync again. //patcher

thanks for that patcher...
